'F' lets you get to the file typing menu where you can type a mesh file name and load it by pressing 'enter' when you have spelt out the name correctly.
'V' toggles between the vertex3d vs vertex2d modes. 'C' toggles culling face on or off.
'X' toggles between the polygon modes: point, line and fill. 'Esc' closes the program.
More updates coming soon, until then, enjoy this No Face feels gif.
